The mostly self-centring, frictional and play-free clamping sets with their low moments of inertia are lightweight, compact and said to be easily installed. With their broad range of models they cover virtually every application in tooling and engineering. According to Norelem, they are even applicable for heavy torques. Clamping sets are made of steel, particular models made of stainless steel. They are available ex warehouse with shaft diameters of 4 mm to 85 mm.

The clamping sets consist basically of two feather-shaped rings; the interior and exterior of a set are cylindrical. They are inserted with play into the bore of the hub or threaded onto the shaft. Depending on the type several screws or a central nut wedge or squeeze the conical surfaces of the inner and outer ring against one another in the axial direction. Then with the requisite tightening torque the clamping sets are firmly fixed and secured against axial displacement on the shaft.

Depending on the item, the clamping sets recently included in the product line are said to stand out because, for example, with their compact design they require only minimum surface pressure, can be sunk in a hub connection, are suitable for very thin-walled hub components or have an increased tolerance range for shaft and hub. Shrink discs are suitable for connecting a hollow shaft to a shaft.
